How Long Would It Take A Torn Ligament In Ankle To Heal?

hello i am 37 weeks preganat and I sprained my ankle about 2 weeks ago, and the dr. says that I have torn my ligaments really bad. my question is how long will it take to recover? I have had really bad sprains before {about 40 in my life, I'm 26} and this times seems really bad I can barley walk after two weeks.
